Pregnancy, lactation, and weaning result in dramatic changes in maternal calcium metabolism. In particular, the increased calcium demand during lactation causes a substantial degree of maternal bone loss. This reproductive bone loss has been suggested to be largely reversible, as multiple clinical studies have found that parity and lactation history have no adverse effect on post-menopausal fracture risk. However, the precise effects of pregnancy, lactation, and post-weaning recovery on maternal bone structure are not well understood...

PURPOSE: Lacrimal gland lesions have diverse pathologies. Bone remodelling on imaging may suggest a benign lacrimal gland pleomorphic adenoma (LGPA) rather than a malignant process. METHODS: The authors report a case of malignant pleomorphic adenocarcinoma, which was misdiagnosed clinico-radiologically as a benign LGPA. Lesions with bone remodelling on CT imaging were subsequently analysed amongst a cohort of 31 lacrimal gland lesions from a single tertiary centre...

STUDY DESIGN: Biomechanical investigation. PURPOSE: Cervical two-level corpectomies with anterior-only instrumentation are associated with a high rate of implant-related complications. These procedures, therefore, often require an additional dorsal instrumentation to prevent screw loosening. Cement augmentation of the anterior screws in two-level corpectomies might stabilize the construct, so that a second dorsal procedure could be avoided. To evaluate the screw anchorage in cervical anterior-only procedures, an ex vivo evaluation of the range of motion (ROM) in two-level corpectomies (C4 and C5), with and without cement augmentation of the anterior screws, was carried out in this study...

Metal implants for osteosynthesis are nowadays standard in orthopedic and trauma surgery. Steel implants, especially cerclages, bands and wires, can show more corrosion due to friction and lead to encapsulation in connective tissue with fluid borders even without loosening. Corrosion and fluid borders are potentially more susceptible to incompatibility and infections. Titanium implants have the advantage of better allergic compatibility. Problems may occur in material removal, especially with titanium implants because material fractures occur more frequently...

Differentiated carcinomas of the thyroid gland usually have a good prognosis with prognosis often discussed in terms of 20 year survival. Nevertheless its 10-year-survival rate decreases when accompanied by distant metastasis. Follicular thyroid cancer (FTC) is the second most common thyroid cancer and usually presents with a solitary thyroid nodule with or without cervical lymphadenopathy. Distance metastasis at initial diagnosis is seldom observed with incidence range from 1 to 9%. In cases of bone metastasis, the incidence is only 2-3% and weight-bearing skeleton is preferentially affected...

Semaphorin 3E (Sema3E) plays a crucial role in axon guidance, vascular patterning, and immune regulation. Nevertheless, the role of Sema3E in asthma is still elusive. In this study, we show that genetic ablation of Sema3E in mice results in increased lung granulocytosis, airway hyperresponsiveness, mucus overproduction, collagen deposition, and Th2/Th17 inflammation. Transfer of Sema3e(-/-) bone marrow progenitor cells to irradiated wild-type (WT) recipients exacerbates airway hyperresponsiveness and inflammation, whereas transfer of WT bone marrow progenitor cells ameliorates asthma pathology in Sema3e(-/-) recipients...

Leukemia cells in the bone marrow (BM) must meet the biochemical demands of increased cell proliferation by continually adapting to fluctuations in nutrient and oxygen availability. Thus, targeting metabolic abnormalities in leukemia cells located in the BM may provide an effective therapeutic strategy. In this study, we report the discovery of a metabolic role for BM adipocytes in supporting the growth of leukemic blasts. Preventing nutrient starvation-induced apoptosis of leukemic cells by BM adipocytes, as well as the metabolic and molecular mechanisms involved in this process, were investigated using various analytical techniques...
